Deploying modern web apps (apt vs pip/rvm)
Hi there, We're building (and deploying) a large scale app (python+rails+mongodb) and others. Now developers are running rampant install python dependencies from pip, and ruby stuff with rvm...etc. Some of the packages needed, are in apt repos, some are older versions, and some are not there at all. Now I'd like to pick the pool of expertise here: - Where do we draw the line, between using OS packages vs pip/rvm - How do we best ensure same environment on dev env, vs production env - What are the best practices here Thanks for sharing -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

Re: [Bug 1094019] Re: Linux's getdents gets /.. inode number from host system under LXC
Ok I see, will use block backed lxc then. Thanks On Wed, Jan 2, 2013 at 6:32 PM, Serge Hallyn 1094...@bugs.launchpad.netwrote: Ok, sorry, I see now. Yes i can reproduce this with getdents of course. This has nothing to do with lxc lying, and yes if you need to work around this you'll need to use blockdev-backed rootfs for the containers. The container is set up with the tasks pivot_root'd into the container's /, which in your case is a bind mount. Resolution of '..' respects the fact that the /var/lib/lxc/container/rootfs should be root, and returns itself. However, there is only one actual directory entry for /var/lib/lxc/container/rootfs in all the kernel, and it's '..' (d_parent) points to /var/lib/lxc/container. Lxc can't do anything about that. The kernel's flexible mounts, bind mounts, and mounts namespaces provide different *views* of the filesystems, don't change what is in the actual filesystems. ** Changed in: lxc (Ubuntu) Status: New = Won't Fix -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1094019 Title: Linux's getdents gets /.. inode number from host system under LXC Status in “lxc” package in Ubuntu: Won't Fix Bug description: Calling getdents on / gets the host system's inode number for /.., which is different from /. unlike real (non lxc) systems.

Here is an inadequate attempt: * source code hosting (github, gitosis, etc) - characteristics? * checkpointable (i.e. Mark's single point backup gitosis vms) - qcow2 or qed based for snapshotting? * web hosting - characteristics? * Network performance (hard to generalize) - vpn - various appliation layer/tiers - characteristics? * db hosting - characteristics? * desktop virtualization - ideally, using spice? Yes, but i haven't tried yet since installation is not 'standard' yet. http://www.linux-kvm.com/content/spice-ubuntu-wiki-available - should survive unexpected host reboots? This is something REALLY important which, as far as i know, is better managed with RedHat too :-(. I nearly died when I accidentally typed 'reboot' in the wrong terminal (after which i installed molly-guard everywhere) and when i noticed there was no clean shutdown of the guests; Note that as of very recently, all your libvirt-managed VMs at least should cleanly shut down before the host finishes shutting down. Though I was thinking more of using caching and journaled filesystems, and perhaps even the fs on the host. more even: that reboot corrupted some of the running windows-Vms... I did some research on that, but didn't find time to properly synthetise it and implement the stuff I found (basically, the init scripts used in redhat as far as i remember). https://exain.wordpress.com/2009/05/22/auto-shutdown-kvm-virtual-machines-on-system-shutdown/ http://www.linux-kvm.com/content/stop-script-running-vms-using-virsh https://help.ubuntu.com/community/KVM/Managing#Suspend%20and%20resume%20a%20Virtual%20Machine * windows workloads ? - characteristics? I'll probably put these up on the wiki soon so we can all edit, but in the meantime if you have any suggestions for improving the grouping or filling in characteristics, please speak up. I noticed that most of my load is due to cpu wait: disk IO I guess. Most troubles with too much 'wait' are due to windows VMs. All my VMs use qcow2. There is an option, when you create the disk images When running kvm by hand, I almost always use raw. The vm-tools which I use very frequently use qcow2. It's worth publicizing some (new) measurements of performance with qcow, qed, and raw (both raw backing file and raw LVM partition), upon which results we can base recommendations for these workloads. Any votes for which benchmark to use? Likewise, something like kernbench on two identical VMs, one with swap, and one without, would be interesting. Heck, memory and smp configurations, smp=1/2/4/8 and -m 256,512,1024 would be intereseting. Though we'll ignore what I've used before, having -m 4096 and doing all work in tmpfs :) That was nice and quick. Finally, virtio and fake scsi might have some different effects on the usual filesystems, so maybe we should compare xfs, jfs, ext4, ext3, and ext2 with each. That's getting to be a lot of things to measure, especially without an automated system to do system install/setup/test/compile-resultscough, but heck, we'll see if I end up re-writing one :) manually, to 'preallocate', which is supposed to increase the performance a lot: -o preallocation=metadata : From KVM I/O slowness on RHEL 6 http://www.ilsistemista.net/index.php/virtualization/11-kvm-io-slowness-on-rhel-6.html Hm, this would be worth measuring and publicizing as a part of this. I always choose not to preallocate, and use cache=none. Just how much does performance change (in both directions) when I do preallcoate, or use cache=writeback? So, if you are using Red Hat Enterprise Linux or Fedora Linux as the host operating system for you virtualization server and you plan to use the QCOW2 format, remember to manually create preallocated virtual disk files and to use a “none” cache policy (you can also use a “write-back” policy, but be warned that your guests will be more prone to data loss). If you can confirm this article, then I guess this should be a default option when creating disk images from the GUI VMManager If we can tie the results for certain configurations to particular workloads, then we could perhaps go a bit further. thanks, -serge I haven't been following this thread closely, but my understanding is that we're after testing KVM in lots of different situations? If that is something that can benefit from community contribution

It would seem in general that the database section is woefully lacking in detail compared to other chapters. Paul Hi everyone, So I got two questions that I'd like to answer publicly 1- What is our deadline 2- What is the depth needed for the review My answer is 1- I'm no docs expert, but I checked and Oneiric documentation string freeze is Sep 15th. Allowing for 10 days for merge proposal discussions, we would have only *two weeks* starting today (22Aug-5Sep) to get all the content you would like to review in a ready to merge state from your perspective. As you can see this is not a lot of time, so your prompt help is needed Documentation string freeze is for documentation shipped in the archive. A few release cycles ago we removed the ubuntu-serverguide package and the guide is provided via help.ubuntu.com now, so we should have more time. That doesn't mean people shouldn't start working now, but it's not yet critical. So I should be okay for making some major changes to the chapter? If we're focussed on short term there are just a few small changes to make that I could do in about 5 minutes at lunchtime and commit. I should be able to get the MySQL section sorted in greater detail within about a week, maybe two at the outside. Postgresql will take me longer as I'm unfamiliar with it, but it's been something I've been meaning to learn (however if someone else wants to run with it, let me know.) I think the first priority should still be to verify the current content is correct for 11.10/Oneiric and to address bugs the people have filed. We do have time for more than that however. It's difficult to find a correct balance between Here's how to do it in a good, reliable way that works on Ubuntu, but it's only suitable for very narrow use cases and Oops, just replicated the upstream documentation and confused new people. I think some thoughts on different storage engines, why one might pick different ones, and how to get each going on Ubuntu would be useful with pointers to upstream documentation on the details of each. I always like it when someone comes into #ubuntu-server and asks for help, I've been try to X based on random internet HOWTO Y and it doesn't work, I point them at the server guide and say Do it this way and let me know if you have problems and they either don't come back or come back to say That worked, thanks. If you're into MySQL, you probably have a better idea of what X is than I do and you should just go tackle it. Scott K Thanks Scott, well put And just to re-iterate, now that we're not bound by the doc string freeze, we do have a little more time (a little over 6 weeks) till Oneiric is released. So kindly use the time to review/update the docs, and to add any missing important information (to me that would be second priority however). Use your best judgment whether or not a piece of info should go to the serverguide Thanks again for everyone who volunteered .. can't wait to see those merge proposals :) -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

This would include things like checking package names have not been changed, little code snippets actually work...etc. IMO, serverguide should focus on the Ubuntu specific parts and not attempt to replace upstream docs, with appropriate links to upstream docs I understand there's a lot that could be added, however the priority is making sure the info is correct and up to date Thanks all for the commitment and hard work!

EC2 Migrate EBS AMI tool, call for volunteers
Hi everyone, A while back I had sent an email asking for people interested in working on a python tool to help migrate ebs AMIs across ec2 regions. Since then the project has progressed a bit: - Project page is now: https://launchpad.net/ec2-migrate-ebs-ami - Project is now able to launch two utility instances in the two specified regions, and mount the source volume in the source instance - What remains is attaching a destination volume, and sync'ing over contents. More details can be found on the blueprint: https://blueprints.launchpad.net/ubuntu/+spec/cloud-server-n-ec2-migrate-region Development pace has now slowed down significantly, as such I am renewing the call. This is a great way to start getting involved with cloud development, and to join the Ubuntu Cloud and server communities! joining in is easy, you don't even have to know lots of python to start hacking! The steps are very well defined, and I am happy to help with all steps along the way. If you are thinking about it, go ahead and get in touch with me right now (kim0 on irc, kim0 AT ubuntu.com) or join today's irc meeting (6pm-UTC #ubuntu-cloud https://wiki.ubuntu.com/UbuntuCloudMeeting) Thanks -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

Ubuntu Cloud days, call for sessions
Hi everyone, From March 23rd 2011 to March 24th 2011 we are going to host the very first Ubuntu Cloud Days. This is an event of IRC tutorials and sessions, targetted towards users and IT pros interested in using Ubuntu on commercial clouds, or using Ubuntu server to build their own private clouds. My initial target is two days, however we are most certainly not limited to that! So if you're interested in hosting more sessions, please get in touch with me It's a great opportunity to teach, reach out, get feedback and help getting people interested and involved in making Ubuntu the best cloud Operating System. Because of the number of attendees and the open format (questions coming in live), you don't need to prepare a full hour of content, so it's not actually very hard to set up such a session You can find the preliminary schedule at https://wiki.ubuntu.com/UbuntuCloudDays If you are considering to give a session, please get in touch with me or directly edit the timeTable https://wiki.ubuntu.com/UbuntuCloudDays/Timetable Thanks -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

Re: converting lvm based Virtual Machine to qcow image.
I wouldn't really do it that way. The reason being, running applications like a database server, might have unflushed data, i.e. the on-disk data structures would not be fully consistent. I don't really like taking a backup in that state (called crash consistent state). If possible it's always safer to power off before snapshotting, otherwise, at least make sure your applications have flushed all data to disk (mysql can flush and lock tables to do that, but other apps behave differently) Regards On 01/05/2011 11:54 AM, Nikolai K.

about blocking a range of IP addresses. Is it safe to assume that using
hosts.deny is more effective/better than just adding entries to the
hosts file?
The /etc/hosts.{allow,deny} are part of tcp wrappers (ie, inetd/xinetd) and
have very little to do with host resolution (which is what /etc/hosts is
for). Normally, when I need to block an IP address I throw it at iptables
(the firewall) which is the correct place for it in a lot of (read most)
situations.
Don't know what the general consensus is, but I've almost never really
used hosts.deny in real production. iptables just does everything I
need. OP might want to consider this

Hi folks, I've added a UEC FAQ page at https://help.ubuntu.com/community/UEC/FAQ At the moment I've added a couple of questions/answers (what is a cloud, and why can't I upgrade a kernel in EC2 AMI). I used Scott's answer of today. If you have ever been asked a question related to cloud or UEC that people like to ask over and over, please add that question to that page as it should grow with time Regards -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
UEC Book wiki page
Hi folks, As it stands, we have a lot of valuable information about UEC on the wiki, however there is no complete guide that a newbie can read start to finish. I took a first shot at creating one here https://help.ubuntu.com/community/UEC/Book https://help.ubuntu.com/community/UEC/Book#preview Please let me know if we should add/remove/shuffle things around in that page. Moreover, while reviewing all pages we have available, I spotted a few problems (AFAICT) with some of them. Here's a listing I suspect some pages in that table, will actually belong to the book page, and vice versa, so awaiting your feedback *Page* *Problem* UEC/BaseServerIntall https://help.ubuntu.com/community/UEC/BaseServerIntall Where does that fit in ? Is it needed ? UEC/NodeInstallation https://help.ubuntu.com/community/UEC/NodeInstallation Obsoleted UEC/NodeInstallationSeparate https://help.ubuntu.com/community/UEC/NodeInstallationSeparate Obsoleted, Same and older than UEC/NodeInstallation https://help.ubuntu.com/community/UEC/NodeInstallation ?!

Obsoletes UEC/RegisteringNodes https://help.ubuntu.com/community/UEC/RegisteringNodes UEC/SSHKeyAuthSetup https://help.ubuntu.com/community/UEC/SSHKeyAuthSetup Obsoleted Note1: That book should certainly only be created out of existing pages, not copying around any existing data Note2: Do we all agree that it's best to have specific pages targetting specific topics with a top level page such as this Book page collecting them. I think that's the case, and I'd rather refactor any large multi-topic pages into small focused ones Regards -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

Perhaps that general Ubuntu development discussion should land in #ubuntu-devel, while Server-specific development discussion is encouraged (or belongs) in #ubuntu-server. That's just status quo, as far as I'm concerned, though. +1, if all server, Kubuntu, Xubuntu, Edubuntu, etc development had to be discussed on ubuntu-devel it would get quite noisy there. It's easier for people to just subscribe to the more specific development lists they're interested in and keeping ubuntu-devel for the stuff that's common to more developers. Also, traffic on ubuntu-server is quite low, doesn't really sound worth while splitting it into a -devel list :) -Jonathan I think we're all on an agreement here.

Would love to hear your feedback Kind Regards All suggested changes have been applied. I've changed topic on #ubuntu-cloud to remove the redirection to #ubuntu-server Regards -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
